First of all this is a really great shirt and one of a kind - I've never seen anything like it. It is very light and comfortable on hot days and, as mentioned, is excellent for protecting hands from insects and the sun, which is particularly important on the water or at high altitudes where UV rays are very intense. It dries quickly, feels great and you don't even realize you're wearing it. Cons for me: I'm 6ft 3in and 190lbs and usually wear one size large and one size larger when available. fits well on the torso and shoulders, the sleeves are a bit short for my arms which would normally require 34 or 35 sleeves in a shirt. worked better. Too bad there is no large size. Still, great shirt and I plan on wearing it a lot!
